Answer 2

Answer:

Given 24 men working 8 hours per day can do a work in 15 days. So, 24 men working at 8 hours per day can do 2880 units of work in 15 days. So, 20 men working at 9 hours per day do the same work in 16 days.

Step-by-step explanation:

Work =Men × hr/day×days

Work is same in both cases

Let 48 men will complete the same work in x hr/day

20×8hr/day×21=48×x hr/day×7

48x=(20×8×21)/7

48x=20×8×3

x=(20×8×3)/48

x=480/48

x=10

48 men must work 10hr/day to complete the same work in 7 days
